NATHAN LAWRENCE, OF TAUNTON, MASSACHUSETTS, ASSIGNOR TO REED 8v BARTON, OF SAME PLACE.

IMPROVEMENT IN THE CONSTRUCTION OF ICE-PITCHERS.

Specication forming part of Letters Patent No. 70,582, dated November 5, 1867.

To all 'whom it may concern:

Be it known that I, NATHAN LAWRENCE, of Taunton, Bristol county, Massachusetts, have invented a new and Improved lce-Pitcher; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanyingdrawings, forming part of this specification.

Thisinvcntion relates toa new and useful improvementin doublewalled or ice pitchers, such as are constructed ofwhite-metal, and most generally plated.

Hitherto these pitchers have had their inner wall or lining constructed with abottom connected to the body or main portion by means of solder, and these bottoms would very frequently become detached or be parted at their joints or seams so as to leak, owing to the throwing of large linups ot' icc into the pitcher.

This invention is designed to obviate this diiiiculty, and to this end I construct the inner wall or lining with a seamless bottom, and also strengthen the same by means of ribs or with a backingf as hereinafer fully shown and described.

In the accompanying sheet of drawings, Figure l is a vertical central section of myinvention; Fig. 2, a longitudnal'section ofthe same, looking upward, x x, Fig. 1, showing the line of section.

Similar letters of reference indicate corresponding parts.

A represents the outer wall or exterior ot the pitcher, and B the inner wall or lining. The outer wall may be of any desired form, and is of usual construction., The inner wall or lining B, however, is spun or swaged out of a a single piece of metal, so as to have no seams, as shown clearly in Fig. 1. The bottom a ot' this inner wall or lining I strengthen by soldering ribs b to its under side. These ribs may be of any desiredshape or formand they are designed to stifen the bottom a, so that it will not be liable to'be ruptured by lumps of ice when thrown into the pitcher.

At present the inner Walls of ice-pitchers are constructed ot' two distinct parts-the sides or body and the bottom, the bottom being attached to the lower edge of the body by means of solder. The difficulty attending this construction is that the bottom is very liable to be forced out, the soldered seam parting under the fall of the lumps of ice which are carelessly thrown into it. My improvement effectually obviates this difficulty.

I would remark that, instead of having the inner wall or lining composed oa single piece, it may be composed of two pieces united by a horizontal seam. In this case the bottom and lower part of the body will bein one piece, and that is the essential point, as the bottom is the vulnerable part, the sides of the inner wall or lining not being subjected to the blows or concussions of the lumps of ice which may be thrown into it.'

I claim as new and desire to secure by Letters Patentl. An ice or double-walled pitcher having its inner wall or lining spun or swa-ged out,l of one piece of metal or swaged out of a singe piece, so that the bottom will be seamless, or without ajoint, substantially as described.

2. The securing ot' ribs b to the bottom a of the inner wall or lining, substantially as and for the purpose specified.

The above specification of my invention signed by me this 25th day of February, 1867.

NATHAN LAWRENCE.
